Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Determine installed Chrome version
    Open Google Chrome and navigate to chrome://version, or click Help > About Google Chrome. Note the full version number displayed.
    Affected if The displayed version number is less than 12.0.742.91 (for example, 12.0.742.90, 12.0.742.0, or any 11.x/10.x release)
  2. Confirm image loader is in use
    The vulnerability exists in Chrome's image loading subsystem. Any browsing activity that loads images (including viewing websites, opening locally stored images, or viewing email attachments) will exercise this component.
    Affected if Chrome is used to browse websites or view any image content, as the flaw is triggered when processing maliciously crafted images through the image loader

If your Chrome version is below 12.0.742.91 and you use the browser to view images, your environment is affected by this use-after-free vulnerability in the image loader.
